EulerOS 2.0 SP3 : libgcrypt (EulerOS-SA-2020-1400)
medium Nessus Plugin ID 135529
Synopsis
The remote EulerOS host is missing multiple security updates.Description
According to the versions of the libgcrypt packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :- Libgcrypt before 1.6.3 and GnuPG before 1.4.19 does not implement ciphertext blinding for Elgamal decryption, which allows physically proximate attackers to obtain the server's private key by determining factors using crafted ciphertext and the fluctuations in the electromagnetic field during multiplication.(CVE-2014-3591)
- The mpi_powm function in Libgcrypt before 1.6.3 and GnuPG before 1.4.19 allows attackers to obtain sensitive information by leveraging timing differences when accessing a pre-computed table during modular exponentiation, related to a 'Last-Level Cache Side-Channel Attack.'(CVE-2015-0837)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
Solution
Update the affected libgcrypt packages.See Also
